[0038] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0039] Example 1

[0040] refer to Figure 1-4 The present embodiment provides a heat dissipation and exhaust system, which includes a water receiving box 1 and a filter 2. The water receiving box 1 is provided with at least one water receiving tank 11 with an open top. In the present embodiment, the water receiving box 1 is provided with two water receiving tanks 11 arranged at intervals on the left and right. Two first air inlets 121 extending downward are provided at the bottom of the water receiving box 1. The two first air inlets 121 are respectively connected to the two water receiving tanks 11, and the two first air inlets are configured to be respectively connected to the two cooking cavities of the steaming and baking module, so that the cooking cavity can transmit high-temperature steam and oil smoke generated by cooking upward through the water receiving box 1, and ensure that the exhaust heat dissipation of the two cooking cavities does not affect each other.

[0041] Two second air inlets 122 are provided at the positions of the side wall of the water receiving box 1 corresponding to the water receiving tank 11. In this embodiment, the two second air inlets 122 are arranged on the front side wall of the water receiving box 1 at intervals on the left and right, and the two second air inlets 122 are respectively connected to the two water receiving tanks 11. Each second air inlet 122 is configured to be connected to the interior of the stove module to transmit the high-temperature gas or leaked gas inside the stove module to prevent the risk of gas accumulation inside the stove module to the personal safety of users. Of course, each second air inlet 122 can also be configured to be connected to the space at the bottom of the stove module to solve the impact of high temperature and high humidity in a small space on the cabinet wood.

[0042] In this embodiment, a filter 2 is detachably installed in each water receiving tank 11, and the filter 2 only covers the first air inlet 121, and is used to prevent foreign matter or impurities from entering the first air inlet 121, so as to prevent foreign matter or impurities from entering the cooking cavity of the steaming and baking module through the first air inlet 121. Of course, it is also used to filter and cool down the high-temperature steam and oil smoke flowing out of the first air inlet 121. In other embodiments, the filter 2 can be configured to only cover the second air inlet 122, and is used to prevent foreign matter or impurities from entering the second air inlet 122. Of course, the filter 2 can also be configured to cover both the first air inlet 121 and the second air inlet 122.

[0043] refer to Figure 2-5 , further, the filter element 2 has a water tank with an open top (not shown in the figure), and a first vent 22 connected to the first air inlet 121 is provided at a position of the filter element 2 corresponding to the first air inlet 121. In this embodiment, the lower end of the first vent 22 integrally extends downward to form an air inlet end, and the air inlet end is plugged with the first air inlet 121, so that the filter element 2 can be pre-positioned and limited through the first vent 22 and the second air inlet 122 that are plugged in, so as to prevent the filter element 2 from moving relative to the water tank 11. A first filter portion 23 extending upward and covering the first vent 22 is integrally formed on the bottom surface of the water tank, the top of the first filter portion 23 is closed, and a plurality of filter holes 231 arranged circumferentially at intervals are provided on the peripheral wall of the first filter portion 23, and the first vent 22 is connected to the water tank through the filter holes 231 of the first filter portion 23. Therefore, when the high-temperature steam and oil smoke flowing upward from the first air inlet 121 pass through the first filter part 23, they can be diverted into multiple air flows by the multiple filter holes 231 of the first filter part 23, thereby achieving the effect of gas separation and gas uniformity, and at the same time, the oil pollution of the oil smoke and the water content of the high-temperature steam can be reduced, thereby achieving the purpose of oil filtering and cooling.

[0044] refer to Figure 6Furthermore, a water retaining rib 24 extending upward is integrally formed in the water tank, and the water retaining rib 24 divides the water tank into a liquid storage area 211 and an air intake area 212. In this embodiment, the bottom surface of the liquid storage area 211 is in an arc shape with a low middle and high ends. Of course, it can also be a V-shape or other shapes, so as to increase the volume while facilitating the drainage of condensed water and oil to the liquid storage area 211, and prevent condensed water from flowing to the water retaining rib 24 and the air intake area 212. The first filter part 23 is integrally formed in the air intake area 212, and the first vent 22 is integrally formed at the bottom of the air intake area 212, and the first vent 22 is connected to the air intake area 212 through the filter hole 231 of the first filter part 23.

[0045] refer to Figure 5 Furthermore, a shielding portion 13 extending inward and located above the second air inlet 122 is integrally formed on the wall surface of the water receiving tank 11, and the shielding portion 13 is used to prevent foreign matter or impurities from entering the second air inlet 122. In this embodiment, the shielding portion 13 is arranged from the outside to the inside and tilted downward, and is used to guide foreign matter or impurities falling on the upper surface of the shielding portion 13 into the water tank of the filter element 2. In addition, a plane section is formed at the free end of the shielding portion 13.

[0046] Furthermore, a water retaining portion 14 extending upward is fixedly provided on the bottom surface of the water receiving trough 11 . The water retaining portion 14 is located between the second air inlet 122 and the filter element 2 and is arranged close to the second air inlet 122 , so as to prevent condensed water or debris from entering the second air inlet 122 .

[0047] refer to Figure 1-2 The heat dissipation and exhaust system also includes a cover plate assembly 3, which is arranged on the top of the water receiving box 1 and covers the water receiving box 1. An exhaust portion (not shown in the figure) connected to the water receiving tank 11 is provided at the position of the cover plate assembly 3 corresponding to the water receiving tank 11. The exhaust portion is composed of a plurality of exhaust grid holes 311 arranged at intervals. Of course, the exhaust portion can also include an exhaust port and an exhaust filter detachably installed at the exhaust port. In this way, while not affecting the upward exhaust and heat dissipation, the exhaust grid holes 311 or the exhaust filter can reduce foreign matter or impurities from falling into the water receiving box 1.

[0048] In this embodiment, the cover assembly 3 includes an upper cover body 31, which is arranged on the top of the water receiving box 1 and covers the top openings of the two water receiving grooves 11. An exhaust portion is provided at the position of the upper cover body 31 corresponding to the water receiving groove 11, and the two exhaust portions are arranged at intervals.

[0049] refer to Figure 1-2The heat dissipation and exhaust system also includes a heat dissipation fan 41 and a heat dissipation duct 42. The heat dissipation fan 41 is arranged in front of the water receiving box 1, and the air inlet of the heat dissipation fan 41 is respectively connected to the space inside the stove module and the space at the bottom of the stove module. The heat dissipation duct 42 is connected between the heat dissipation fan 41 and the water receiving box 1. The front end of the heat dissipation duct 42 is connected to the air outlet of the heat dissipation fan 41, and the rear end is respectively connected to the two second air inlets 122. Therefore, through the heat dissipation fan 41 and the heat dissipation duct 42, not only the high-temperature gas or leaked gas inside the stove module can be discharged in time to prevent the risk of gas accumulation inside the stove module to the personal safety of the user, but also the high-temperature gas in the space at the bottom of the stove module can be discharged in time to prevent the high-temperature gas from condensing in the space to produce condensed water, which effectively solves the influence of high temperature and high humidity in a small space on the cabinet wood.

[0050] Further, a plug-in portion 421 is formed at the front end of the heat dissipation duct 42, and the plug-in portion 421 is inserted into the air outlet of the heat dissipation fan 41 and the two are sealed and connected by a snap-in structure, which is convenient for disassembly and assembly, and avoids air leakage between the heat dissipation duct 42 and the air outlet of the heat dissipation fan 41. A lower support portion 422 and an upper support portion 423 are formed at the rear end of the heat dissipation duct 42. The lower support portion 422 is located below the second air inlet 122 and abuts against the bottom front side of the water receiving box 1, and is used to reliably support the water receiving box 1 and form a lower support. The upper support portion 423 is located above the lower support portion 422 and abuts against the top of the second air inlet 122, and is used to reliably support the water receiving box 1 and form an upper support, so that the upper and lower support portions cooperate to avoid the formation of a gap between the heat dissipation duct 42 and the water receiving box 1 to cause gas leakage, and ensure that the gas transmitted inside the heat dissipation duct will normally enter the water receiving box 1 through the second air outlet.

[0051] Example 2

[0052] refer to Figure 7-11 , an integrated cooking appliance of this embodiment comprises a steam-bake module 5, a stove module 6 and a heat dissipation and exhaust system as described in Embodiment 1. The steam-bake module 5 has two cooking cavities arranged at intervals on the left and right, and each cooking cavity is provided with a steam exhaust port connected thereto. The stove module 6 is arranged above the steam-bake module 5, and comprises a bottom shell 61 and a panel 62, the bottom shell 61 has a cavity 610 with an open top, and the panel 62 is arranged on the top of the bottom shell 61 and covers the top opening of the cavity 610. The water receiving box 1 is mounted on the panel 62 and is located behind the cavity 610, the first air inlet 121 is connected to the steam exhaust port through the exhaust pipe 51, and the second air inlet 122 is connected to the cavity 610.

[0053] It can be seen that by connecting the heat dissipation and exhaust system to the two cooking cavities of the steaming and baking module 5, the high-temperature steam and oil smoke generated by the two cooking cavities can be discharged upward through the water receiving box 1, and the exhaust and heat dissipation of the two cooking cavities are ensured not to affect each other. In addition, by connecting the heat dissipation and exhaust system to the cavity 610 of the stove module 6, the high-temperature gas or leaked gas inside the stove module 6 can be discharged upward through the water receiving box 1, preventing the risk of gas accumulation inside the stove module to the user's personal safety.

[0054] refer to Figure 9-10 Furthermore, a notch 621 is provided in the middle of the rear side of the panel 62, and a mounting hole 615 is provided at a position corresponding to the notch 621 on the rear side of the top of the bottom shell 61, and the mounting hole 615 is located behind the cavity 610. The water receiving box 1 vertically penetrates the notch 621 and the mounting hole 615, and the water receiving box 1 is fixedly connected to the panel 62 and / or the bottom shell 61, so that the water receiving box 1 is firmly and reliably fixed on the stove module 6.

[0055] Furthermore, an air inlet 611 and a profile 613 extending upward and located at the periphery of the air inlet 611 are provided at the bottom of the bottom shell 61, and at least one air inlet channel 614 is provided on the profile. The heat dissipation fan 41 is arranged in the cavity 610, and the heat dissipation fan 41 is detachably mounted on the top of the profile 613 by screws to firmly fix the heat dissipation duct 42 on the profile of the bottom shell 61. At this time, the heat dissipation fan 41 can be rigidly connected to the top of the profile 613. Of course, the two can also be flexibly connected by a flexible material (such as a silicone pad or a sponge pad, etc.). The air inlet of the heat dissipation fan 41 is connected to the space at the bottom of the bottom shell 61 through the air inlet 611, and the air inlet of the heat dissipation fan 41 is connected to the inside of the cavity 610 through the air inlet channel 614.

[0056] A mounting opening 612 is provided at a position of the rear side wall of the bottom shell 61 corresponding to the water receiving box 1. The heat dissipation duct 42 is transversely arranged through the mounting opening 612 and is detachably connected to the bottom shell 11 by screws. The front end of the heat dissipation duct 42 extends into the cavity 610 and is connected to the air outlet of the heat dissipation fan 41. The rear end of the heat dissipation duct 42 is respectively connected to the two second air inlets 122 on the water receiving box 1.

[0057] Example 3

[0058] refer to Fig.11 The difference between this embodiment and the first embodiment is that the structure of the cover assembly 3 is different. In this embodiment, the cover assembly 3 includes an upper cover body 31, a fixing seat 32 and a sealing member 33. The upper cover body 31 is arranged on the top of the water receiving box 1 and covers the top openings of the two water receiving grooves 11. An exhaust part is arranged at the position of the upper cover body 31 corresponding to the water receiving groove 11, and the two exhaust parts are connected.

[0059] The sealing member 33 is disposed on the top of the water receiving box 1 and is located at the periphery of the two water receiving grooves 11. The fixing seat 32 is disposed between the upper cover 31 and the water receiving box 1, and the fixing seat 32 is sealed and connected to the water receiving box 1 through the sealing member 33, thereby reducing air leakage at the joint between the fixing seat 32 and the water receiving box 1. A through hole 321 for air flow is provided at the position of the fixing seat 32 corresponding to the water receiving groove 11.

[0060] It can be seen that by adding a fixing seat 32 and a sealing member 33 between the upper cover 31 and the water receiving box 1, the heat dissipation and exhaust effect is achieved while improving the sealing effect. However, the structure is relatively complex and the production efficiency is relatively low.

[0061] Example 4

[0062] The difference between this embodiment and the embodiment 1 or 3 is that the filter element 2 is further integrated with a second vent and a second filter portion. Specifically, a second vent connected to the second air inlet 122 is provided at a position of the side wall of the filter element 2 corresponding to the second air inlet 122, and a second filter portion extending inward and covering the second vent is integrally formed on the side wall of the water tank, and the second vent is connected to the water tank through the second filter portion. Since the second filter portion can prevent foreign matter or impurities from entering the second air inlet 122, the shielding portion 13 on the water receiving box 1 can be omitted or not omitted.

[0063] It can be seen that by integrating the second air vent and the second filter part on the filter element 2, the filter element 2 can filter and cool down the high-temperature gas or leaked fuel gas flowing out from the second air inlet 122, and at the same time prevent foreign matter or impurities from entering the heat dissipation duct, the heat dissipation fan or the stove module through the second air inlet 122, thereby preventing foreign matter or impurities from entering the heat dissipation duct or the heat dissipation fan and generating abnormal noise.

[0064] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
